INVESTIGATING THE MULTIPLE RECOLLISION OF THE NONSEQUENTIAL DOUBLE IONIZATION PROCESS

Pham Nguyen Thanh Vinh

Tóm tắt


We systematically investigate the contribution of recollision dynamics to the nonsequential double ionization process (NSDI) of Ar atom for a wide range of laser intensity. The result shows that the first- and second-recollision scenarios have significant contribution to the NSDI events. Moreover, we figure out that the impact of double-recollision trajectories decreases as the laser intensity increases. Besides, many details of multiple recollisions are also investigated in this paper.
